Installing Azure.Communication.Sms package into my asp.net app

Lino Vlacic 41

Hi,

I created a Communication Service in my Azure account, and was given a telephone number to use.
Now I want to use it in my asp.net app.

I want to send text messages to cell phones from my app. I understand I need to install Azure.Communication.Sms

I cannot find this package when using NuGet from within my asp.net app. How to I install this package?

Thank you for any help.

@Lino Vlacic ,

While still in the application directory, install the Azure Communication Services SMS SDK for .NET package by using the dotnet add package command.

Use this command:

dotnet add package Azure.Communication.Sms --version 1.0.0

Add a using directive to the top of Program.cs to include the Azure.Communication namespace.

using System; using System.Collections.Generic; using Azure; using Azure.Communication; using Azure.Communication.Sms;

If you haven't done this already, kindly checkout this doc steps- section for Setting up.

Please let us know if you have further questions on this.

Hi, Thank you for your response. I tried that multiple ways. It keep coming back with errors. 'Project not found'

I I think it's looking for for project .csproj but I have solution: .sln

This is what I get:

C:\Projects\PurePressureWash>dotnet add package Azure.Communication.Sms

C:\Projects\PurePressureWash\website.publishproj(47,3): error MSB4019: The imported project "C:\Program Files\dotnet\sdk\3.1.302\Microsoft\VisualStudio\v16.0\Web\Microsoft.WebSite.Publishing.targets" was not found. Confirm that the expression in the Import declaration "C:\Program Files\dotnet\sdk\3.1.302\Microsoft\VisualStudio\v16.0\Web\Microsoft.WebSite.Publishing.targets" is correct, and that the file exists on disk.

@Lino Vlacic , Apologies the issue is still not resolved. I understand you have already tried multiple approaches.

The error is probably because you have a .Net Framework web app (with old style .csproj), instead of a .net core app (with sdk-style csproj). Kindly review this.

When you do a NuGet search in VS, what exactly do you see - could you please share a screenshot after concealing any private details (just like below).

Also, just to isolate, ensure that VS is up-to-date and system has all the latest updates. For a quick test/to isolate the issue, you may check this on a different system running VS.

My app is .net frameworks (not core). And I am running Visual Studio 2019, all updates fine. On Windows 10.

strong text
This is the file I used: azure.communication.sms.1.0.1.nupkg

I tried attaching screen shot but it did not work. I really need to get to the bottom of this.

This is the error:

Severity Code Description Project File Line Suppression State
Error Could not install package 'Azure.Communication.Sms 1.0.1'. You are trying to install this package into a project that targets '.NETFramework,Version=v4.5.2', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.

Thanks for the follow-up.

Just to confirm, from the error the app is targeting .NET Framework 4.5.2, but the Sms package targets .NET Standard 2.0. Please confirm if you're on at least .NET Framework 4.6.1 to use it (https://learn.microsoft.com/dotnet/standard/net-standard).

I have also added additional VS tags to receive insights from VS SMEs/community.

Apologies for the issue you encountered uploading the screenshot, I'll ensure to relay the feedback with the platform team.

Having mentioned above, I'll connect with you offline to provide focused assistance on this.

Hello @Lino Vlacic , have you tried @ajkuma ’s suggestion(check and use the .NET Framework version 4.6.1+)? You can check the target framework version of your project by right-clicking your project > Unload Project > right-clicking your project again > Edit Project File. From the project file, you can see the specific target framework version between <TargetFrameworkVersion> tag and </TargetFrameworkVersion> tag.(You can then reload your project after these operations to continue to develop, by right-clicking your project > Reload Project)

I resolved this issue by upgrading to .NET Framework 4.6.1. But now I have new issue.

I installed Azure.Communication.Sms successfully. And my 3 lines of code compile fine and app builds successfully.

But when I execute, I get error: "Retry failed after 4 tries. Retry settings can be adjusted in ClientOptions.Retry."
These are my 3 lines of VB.net code:

Dim MySMSClient As SmsClient = New SmsClient(myConnString)

Dim MysendResult As SmsSendResult

'it fails on this line:
MysendResult = MySMSClient.Send(from:="+1929xxxxxxx", [to]:="+1917xxxxxxx", message:="Hello World via SMS")

Any help would be appreciated.

To benefit the community. Posting our offline discussion.

The underlying issue was resolved by upgrading to .NET Framework 4.6.1.

Cause: SMS SDK is written in C# thus it does not support Visual Basic.
Also, sending SMS message was not supported by the phone number that was initially used.

Resolution: Wrote SMS send function in C# and added it to Visual Basic project as a module.
Also, a toll-free number that can send & receive SMS message. was purchased.

Yes, ACS doesn’t support visual basic directly, so the recommend option is to just using REST APIs.

For a reference, use the API call sample.
